Source: Henley and Partners Holdings, https://www.henleyglobal.com/citizenship/visa-restrictions/ Visa Restrictions Index, 2011There is a wide variety of regulatory regimes controlling the
movement of foreign nationals. One such restriction concerns the
emission of a visa granting temporary access to a visitor as long as
the purpose of travel is leisure or business. While the nationals of
developed countries tend to have few traveling restrictions, those
of developing countries tend to have limitations with less countries
open to travel without a visa. A national of Denmark can travel to
173 countries or territories without a visa while a Chinese national
can only travel to 40 countries without a visa. The rule of the
thumb is that developed countries impose travel restrictions on
nationals of countries that have a high likelihood of using the
pretense of tourism or business travel to emigrate. As economic
development takes place, travel restrictions tend to become less
stringent.
